Preparation of anti-knock additive on the basis of super dispersed water-coal suspension

The method of preparation of additive in gasoline on the basis of super dispersed water-coal suspension (WCS) is considered. The method is based on the use of acoustic cavitations effect for dispersion of ultrafine coal powder with water in order to obtain a new water-coal suspension and re-dispersion stage of WCS with gasoline. The additive has improved antiknock properties and is characterized by increased environmental friendliness in comparison with analogues. The additive is resistant to delamination.
